Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Rub the chicken breast evenly with the ghee, then season with half of the oregano, garlic powder, sea salt, and black pepper.
Place the chicken on the baking sheet and roast for 18 to 22 minutes until the internal temperature reaches 165°F.
While the chicken is roasting, heat the olive oil in a large skillet over medium-high heat.
Add the ground beef to the skillet, breaking it into small crumbles with a spatula, and cook until fully browned.
Stir in the diced zucchini, red bell pepper, and red onion, sautéing for 5 to 7 minutes until the vegetables are tender-crisp.
Season the beef and vegetable mixture with the remaining oregano, garlic powder, salt, and pepper.
Remove the chicken from the oven, let it rest for 3 minutes, then slice it into thick strips.
Plate the beef and vegetable sauté and top it with the roasted chicken slices, finishing with a garnish of fresh chopped parsley.
